How is Salinity Calculated?

By Mark Kennan

Instructions

Measurement

Step 1:
Salinity is measured in grams of salt per kilogram of water. For example a salinity of two would mean there were two grams of salt in every kilogram of water.

Salinity vs. Depth

Step 1:
Salinity increases as depth of the water increases because higher concentrations of salt increase the density of water.

Halocline Layer

Step 1:
The halocline layer is found between the surface layer and the deep sea layer of water. This is the level at which the salinity of water rises the fastest.

Electrical Conductivity

Step 1:
The salinity of water can be determined by how easily electricity travels through it. The higher the conductivity the higher the salinity.

Salinity in Aquariums

Step 1:
Many fish require a certain salinity level to live so in fish tanks the salinity level must be kept constant.

What Is the Right Salinity for Salt Water Tanks?

Saltwater fish tanks can enthrall and relax with vivid colors and quirky animals. They can also be a lesson in chemistry. The constant measuring and supplementing can be challenging but also rewarding. One of the most important parameters is salinity.

How to Turn a Fresh Water Tank Into a Salt Water Tank

Very few ornamental fish can survive in both freshwater and saltwater, but some aquarists enjoy the challenge of converting an established freshwater ecosystem into a brackish or saltwater environment. This conversion may be necessary for species like...

How to Take Care of a Saltwater Fish Aquarium

Saltwater aquariums can be a great alternative to freshwater aquariums in that they often can provide a wider variety of options for the type of fish bought. However, saltwater aquariums require a different kind of maintenance than freshwater aquariums...

Plants add visual appeal to a fresh water aquarium. They also convert CO2 into oxygen, helping to keep the water aerated for the fish. Growing plants in an aquarium makes for a more natural eco-system within the tank, resulting in healthier fish. By...

Brackish water is water that has lower salinity than seawater but higher salinity than fresh water. Brackish water occurs naturally in areas where fresh water and saltwater mix, such as the point where rivers flow into oceans. Some types of fish, such as...
